Connector Shielding Cage Spring Sheet Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-speed electrical connectors require additional components like conductive gaskets and fixation plates to achieve effective electromagnetic shielding, increasing assembly complexity and cost.
Innovation Solution
A shielding cage design with spring sheets that extend both inside and outside the opening, eliminating the need for conductive gaskets and fixation plates by using outer spring sheet portions for direct elastic and electrical contact with the apparatus housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring sheet is provided inside the opening of the shielding cage to limit electromagnetic interference, then the anti-electromagnetic interference performance is improved, but additional components (conductive gasket and fixation plate) are required which increase assembly complexity and cost
Solution Approach 1:
The patent combines the spring sheet with the shielding cage by extending it from inside to outside the opening, merging two previously separate components (spring sheet and shielding cage) into an integrated structure. This eliminates the need for separate conductive gaskets and fixation plates, directly resolving the technical contradiction by maintaining electromagnetic shielding performance while reducing assembly complexity
Solution Approach 2:
The extended spring sheet performs multiple functions simultaneously: it provides electromagnetic shielding inside the opening, acts as a conductive connection to the apparatus housing outside the opening, and serves as a fixation element. This multi-functionality eliminates the need for separate specialized components, resolving the contradiction between reliability and device complexity
